<p>A radio base station according to the present invention is equipped with a determination unit that compares a first signal quality of a first output signal which is output by an adaptive array antenna and a second signal quality of a second output signal which is output by an adaptive equalizer and determines whether the improvement effect of the second signal quality with respect to the first signal quality is below expectation. When the determination unit determines that the improvement effect is below expectation, a controller stops power supply to the adaptive equalizer and the calculation of an equalization weight by a weight calculator, and outputs the first output signal as the output signal of a receiver.</p> |
